Xorg ATI drivers failure

To my understanding, the ati driver under Xorg is a wrapper that selects the appropriate driver for an ati graphics card. My Dell Inspiron 3800 has an ATI Rage Mobility P/M 8MB AGP 2x graphics chipset which is supposed to work with the mach64 driver.

 

In other Linux distrobutions such as Gentoo and Ubuntu, selecting the ati driver under Xorg loads up the mach64 drivers, (same effect when instead of ati as the driver in Xorg.conf, you put atimisc), and everything works fine. In Mandriva, however, selecting the ati driver under Xorg, (the wrapper), attempts to load up the mach64 driver but fails with the following error:

 

(EE) ATI(0): [dri] ATIDRIScreenInit failed because of a version mismatch.

[dri] mach64.o kernel module version is 0.0.0, but version 1.0 or greater is needed.

[dri] Disabling DRI.

 

Am I right to suspect that the mach64 drivers that come with Mandriva are somehow "corrupted" or missing, or did I fail to see something to allow the mach64.0 kernel module to be present and working?

Hi Timothy,

 

a version mismatch error of this kind is caused by the kernel. ATI drivers which are not derived from the xorg project must match the kernel version *exactly*, i.e. you cannot use driver modules compiled for 2.6.12.16 in kernel 2.6.12.17 and so on. By installing dkms-ati the building and install process of the correct module is done automatically. (You'll probably have to add/update PLF software repositories first - see easyurpmi for this.)

 

Errors can occur within the building process, though. In that case, follow the instruction from error message to remove the faulting condition. In many cases this is quite simple, just invoking few commands to prepare kernel sources for a proper build. If you're unsure or it won't work, please post that output here, adding kernel and driver version.

 

Good luck,
